- Habitat
- Deep blue water off continental shelf. Spends days in depths and nights near surface. Fish of twilight zone following vertical migration of squid in open ocean environments globally.
- Range
- Worldwide distribution. In New Zealand found in deep blue water off continental shelf particularly north of North Island. Most common in northern waters during summer months at southern edge of range.
- Endemism
- Native
- Main Threats
- Commercial longline fishing is primary threat with large numbers caught as target and bycatch. Overfishing and climate change affecting prey distribution patterns significantly across global range.
- Population
- Not Threatened globally but rare in New Zealand waters. At southern edge of range here so special catch. Most taken by longliners targeting tuna but few lucky anglers hook them each year.

- Not Threatened
The gladiator of the open ocean. A fish with a sword. It is unmistakable. A massive cylindrical body defines the shape. A tall swept-back dorsal fin cuts the water. That famous bill is flattened and sharp as a blade. It makes up nearly a third of the fish's length. Dark metallic blue-black covers the back. It fades to silvery brown on the belly. Huge eyes are adapted for seeing in the dim light of the deep sea. A fish built for combat. The morphology suggests aggression. The function is precision.
Deep divers with a taste for squid. Swordfish spend their days in the cold dark water. They go 500 metres down or more. They feed on squid, fish and crustaceans. At night they follow the food up to the surface. This is where they are sometimes caught by anglers drifting under the stars. They use that bill to slash at schools of fish. This stuns or injures prey. They turn around to eat them. A sword that is also a tool. The weapon serves the meal. The violence is efficient. The energy cost is low.
The fish of the night drift. Head out before sunset. Set baits deep and wait. Hours pass. Stars come out. Then, without warning, the reel screams. The line peels off. The fish is on. The tension is immediate. The struggle is prolonged. The darkness hides the opponent. The sound reveals the power. The rod bends. The drag clicks. The night comes alive.
To catch a swordfish is to catch a legend. The fish with the sword. The gladiator of the deep. The one that makes a person forget how tired they are. And how far they have come. The fish of the night watch. The one chased when the moon is right. When the current is slack. And the willingness to stay up all night for a single glorious run of the reel is there. The dedication is total. The reward is singular. The memory is permanent.
The stars are out. The water is dark. The reel screams. The line goes tight. The swordfish leaps. The sword glints in the moonlight. Then it is gone. Or it is not. Either way, the story begins. The narrative is crafted in the telling. Not just the catching. The image persists. The silver flash. The dark water. The silent boat. The exhausted angler. The tale grows with each retelling. The facts may blur. The feeling remains. It is a trophy of endurance. Not just size. The swordfish represents the limit. The edge of the map. The depth of the night. It carries on.
